When cleaning up the artifacts of a list being deleted, be more careful for

artifacts that don't exist.  In that case, just skimp them rather than
complain.

Docstring style cleanup.

Allow for doctest layer specification in the package's __init__.py, defaulting
to SMTPLayer if not given.  This is probably too coarse for long term use, but
it works for now.

Make sure pipelines.txt properly cleans up its digest; it must be flushed
after clearing.
